{"product_id":"cogalois-theory","title":"Cogalois Theory","description":"This volume offers a systematic, comprehensive investigation of field extensions, finite or not, that possess a Cogalois correspondence. The subject is somewhat dual to the very classical Galois Theory dealing with field extensions possessing a Galois correspondence. Solidly backed by over 250 exercises and an extensive bibliography, this book presents a compact and complete review of basic field theory, considers the Vahlen-Capelli Criterion, investigates the radical, Kneser, strongly Kneser, Cogalois, and G-Cogalois extensions, discusses field extensions that are simultaneously Galois and G-Cogalois, and presents nice applications to elementary field arithmetic.","brand":"Taylor \u0026 Francis Inc","offers":[{"title":"Default Title","offer_id":54224830857560,"sku":"9780824709495","price":328.6,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/1295\/4195\/files\/9780824709495_1e805636-0473-4fe4-8715-e156e6e3c076.jpg?v=1779333339","url":"https:\/\/agendabookshop.com\/products\/cogalois-theory","provider":"Agenda Bookshop","version":"1.0","type":"link"}
